The system and feature of the main structure were described. Analysis results of the crossover were emphatically introduced. Strengthened design measures were put forward corresponding to influence of slab thickness, the control of twin-tower subsidence differences, the prevention of the progressive collapse and the construction process simulation. These measures include improving the stiffness and strength of each tower and setting proper construction process before the form of the stiffness of crossover.Keywords: complicated high-rise building; multi-tower structure; design of the crossover作者简介:严敏,高级工程师,Email:min_yan@ecadi.com。连体结构是复杂高层建筑中较为典型的类型,通常意义上的连体结构分为弱连接结构和强连接结构,强连接结构大多通过连接体将两栋或多栋塔楼进行刚性连接。已建成的连体结构中由两个非对称单塔进行刚性连接的超高层建筑并不多见,其连接体部分的设计和分析尤为重要。本文将结合作者的工程设计实践,介绍非对称刚性连体超高层建筑——苏州“东方之门”结构工程的设计体会。参考文献[1] 严敏,张家华,芮明倬,等.非对称门式双塔连体超高层结构计算分析[J]. 建筑结构,2008,38(12):84-86.[2] 徐培福,傅学怡,王翠坤,等. 复杂高层建筑结构设计[M]. 北京:中国建筑工业出版社,2005.[3] 吴晓涵,刘东泽,芮明倬,等. 非对称刚性连体超高层结构弹塑性时程分析[J]. 建筑结构学报,2010,32(6):1-9.
